Karl Dungs FRI Pressure Regulator
The Karl Dungs FRI pressure regulator combines the functions of pressure regulation and a filter in one housing. In addition, the FRI has (2) downstream pressure ports for gas switch installation or pressure sensing. Can be installed as a stand along regulator, or incorporated into a Karl Dungs DMV style pipe train.

Features:

  1. UL, CE and CSA certified.
  2. Lock up style regulator, so no downstream pressure builds up under no flow conditions.
  3. The FRI double diaphragm design and vent limiter eliminates the need for vent piping outside a given building.
  4. The FRI will handle up to 7 PSI maximum inlet pressure.
